Abstract
Understanding human visual attention is a cornerstone for creating engaging experiences. This task remains complex, especially within immersive environments where users behave under varying levels of cognitive load. We analyze gaze data recorded by Pina et al. [1] during an experiment where users perform a multisensory visual search task in VR under different levels of cognitive load and search areas. We focus on gaze behavior under changes on those environmental variables, based on some metrics inspired by Malpica et al. [2] regarding fixations and saccades.
Conclusions and Future Work
We corroborate the contrast oy gaze behavior between different search areas. Regarding the influence of cognitive load, we find lower saccade amplitudes and eye eccentricity as CL increases, which aligns with the decrease in performance observed by Pina et al. [1] and suggests some mechanism of sensorimotor economy, already known in attention research [3]. Future avenues include the study of pupil dilation, blinks, and the correlation of gaze features with other physiological signals, as well as some applications in real time.
